I thought I'd get a few pictures out of the first 5 completed cap types.
On the right half, I staggered the columns to their approximate position. Because of the rather aggressive stepping of the different rows I chose not to have as aggressive of a column stagger as I had originally designed. The taller rows made it clumsy to move fingers across columns if there was too much of a column stagger because of the height difference.
In the background you can see a bag full of dud caps. I probably culled about 50% of the caps I cast. As I made more I figured out some of the reasons some failed and by the end I was batting about .900. Because the resin was so fast to set, I had to learn how much time I had to stir so that it was well mixed but still quick enough to have a good flow on the pour.
I may come back and cast a few more for spares and to replace some of the more marginal caps.
Another view. You can see the different sheen on a few of the caps. I think I put too much mold release on them and it affected the finish. The aluminum masters are in a row in front
There are some noticeable flaws in the bottom row caps. For some reason, if the master and the mold is flawed, the castings don't get any better no matter how many caps you make with it.
If I have time I'll fix the master and remold it.
